There is UPS Pico [1] for rPi3/4 that does that job well + a bunch of other features (fan control, some extra IO, supercap+battery support, watchdog and few other).
There are also few simpler ones that do "just" supply power and "power good" signal.
There is also plenty of DC UPSes, although often targeting the industry, which means "expensive"
In-between is [2] OpenUPS but I didn't used it. It's just pretty niche product and niche is also one of the "it will be expensive" keywords.
Soo yeah, they are out there and work fine, go and buy one. Oh, don't want to spend more than rPi ? Well, that's the price of niche products, even if parts are not super expensive it need to cost enough for NRE costs to amortize.
Or, slap a power strip and few power supplies into normal UPS and call it good enough
